Faheem Ansari, also known as Mohammad Faheem Ansari, is an Indian national who was alleged to be a member of Lashkar-e-Toiba (LeT), an organisation considered terrorist by India and the United States, among others. He was arrested on 10 February 2008 along with five others, charged in connection with the 2008 Mumbai attacks, and later acquitted.
Ansari's family was originally from Uttar Pradesh, but he was born and raised in Mumbai. He is married to Yasmin, with whom he has a daughter, Iqra. He joined the Lashkar e Toiba in 2003 while working in Dubai. In 2007, he returned to Mumbai and stayed there for about three months. Though his parents and brothers were residing in the Goregaon suburb of the city, he made no attempt to contact them during his entire stay. He first stayed at a guest house in Grant Road, but after a few weeks rented a small accommodation. Ansari had initially planned on renting an accommodation in Colaba, but due to the high rent there, decided to settle at Grant Road.
The Mumbai police alleged that Ansari did a reconnaissance of several prominent Mumbai landmarks, including the , the Mumbai police headquarters at Crawford Market, the Maharashtra police headquarters at Colaba, the Mahalakshmi Temple and the Siddhivinayak temple. Ansari went to the Taj Hotel and Oberoi Trident as a tourist and shot video footage of the interiors. He also videotaped the Chhatrapati Shivaji Terminus and the Nariman House, and hand-drew the maps of all the 26/11 targets. In December 2007, Ansari travelled to Kathmandu, where he met and handed over the material to his associate, Sabahuddin Shaikh. He then travelled on a Pakistani passport to Karachi and gave the maps to an LET member named Muzammil.
